Contact
Bug reports, calculation errors, feature requests, privacy or copyright requests, or just general feedback — leave it in the form below. Since this is an individually-run service, there's no separate public email address; this form is the only way to reach the operator.
If you'd like a reply, please include a way to reach you (email, etc.). Without one, your message will still be read but may not get a direct response. Messages are usually checked within a few days, but please understand that replies may take longer since this is a one-person operation.
